Alzheimer's drug hailed as momentous breakthrough
LONDON — The first drug to slow the destruction of the brain in Alzheimer's has been heralded as momentous and historic.The research breakthrough ends decades of failure and shows a new era of drugs to treat Alzheimer's — the most common form of dementia — is possible.Yet the medicine, lecanemab, has only a small effect and its impact on people's daily lives is debated.And the drug works in the early stages of the disease, so most would miss out without a revolution in spotting it.Lecanemab attacks the sticky gunge — called beta amyloid — that builds up in the brains of people with Alzheimer's.For a medical field littered with duds, despair and disappointment, some see these trial results as a triumphant turning point.Alzheimer's Research UK said the findings...

Herpes simplex virus
Cancer-killing virus shows promise in patients
LONDON — A new type of cancer therapy that uses a common virus to infect and destroy harmful cells is showing big promise in early human trials, say UK scientists. One patient's cancer vanished, while others saw their tumors shrink. The drug is a weakened form of the cold sore virus - herpes simplex - that has been modified to kill tumors. Larger and longer studies will be needed, but experts say the injection might ultimately offer a lifeline to more people with advanced cancers. Krzysztof Wojkowski, a 39-year-old builder from west London, is one of the patients who took part in the ongoing phase one safety trial, run by the Institute of Cancer Research and the Royal Marsden NHS Foundation Trust. He was diagnosed in 2017 with cancer of the salivary glands, near the...

Can your blood type predict your risk of having a stroke?
Blood type may affect risk of stroke before age 60: Study
WASHINGTON — People with type A blood may be at higher risk of having a stroke before the age of 60 compared to other blood groups, researchers have found.In contrast, those with blood type O are less likely to have an early-onset stroke, according to the new meta-analysis.The research was carried out by a team led by scientists from the University of Maryland School of Medicine in the United States, who looked at the relationship between genetic characteristics such as blood type and their relationship to stroke.To do so, they looked at data from 48 genetic studies on ischemic strokes in adults between the ages of 18 and 59. Ischemic strokes are caused by a blockage of blood flow to the brain.In total, the studies included around 17,000 stroke patients and nearly 600,000 healthy...

Parents are being advised to get their children vaccinated to help protect against polio.
US doctor issues warning of many undiagnosed polio cases
WASHINGTON — A health official in New York State has told the BBC there could be hundreds or even thousands of undiagnosed cases of polio there.It follows an announcement last month that an unvaccinated man had been paralyzed by the virus in Rockland County, New York.His case has been linked genetically to traces of polio virus found in sewage in London and Jerusalem.Developed countries have been warned to boost vaccination rates.Dr Patricia Schnabel Ruppert, health commissioner for Rockland County, said she was worried about polio circulating in her state undetected."There isn't just one case of polio if you see a paralytic case. The incidence of paralytic polio is less than 1%," she said."Most cases are asymptomatic or mildly symptomatic, and those symptoms are often...

A myth about depression?
LONDON — A study showing depression isn't caused by low levels of the "happy hormone" serotonin has become one of the most widely shared medical articles.It has provoked a wave of misleading claims about antidepressant drugs, many of which increase the amount of serotonin in the brain.This research doesn't show the drugs aren't effective.But the response to it has also sparked some genuine questions about how people treat, and think about, mental illness.After Sarah had her first major psychiatric episode, in her early 20s, doctors told her the medication she was prescribed was like "insulin for a diabetic". It was essential, would correct something chemically wrong in her brain, and would need to be taken for life.Her mother had type 1 diabetes, so she...

The gene, O6-Methylguanine-DNA-methyltransferase, or MGMT, plays an important role in how the body repairs damage to DNA in both men and women.
Gene discovery may explain why more women get Alzheimer's
BOSTON — Scientists have identified a gene that appears to increase the risk of Alzheimer's in women, providing a potential new clue as to why more women than men are diagnosed with the disease.The gene, O6-Methylguanine-DNA-methyltransferase, or MGMT, plays an important role in how the body repairs damage to DNA in both men and women. But researchers did not find an association between MGMT and Alzheimer's in men."It's a female-specific finding -- perhaps one of the strongest associations of a genetic risk factor for Alzheimer's in women," said senior study coauthor Lindsay Farrer, chief of biomedical genetics at Boston University School of Medicine.Two-thirds of the 6.5 million Americans currently living with the devastating brain disease are women, according...

Most skin cancers are caused by too much exposure to ultraviolet (UV) light.
Safe in the sun? UN launches new app to help beat skin cancer
GENEVA — Scientific evidence shows that overexposure to UV radiation is the major cause of skin cancer. To help people protect themselves adequately, a consortium of UN agencies on Tuesday, launched an innovative new App that can help anyone, anywhere, determine the safe amount of time to stay outdoors, soaking up the rays.The SunSmart Global UV App, is the collective brainchild of the World Health Organization (WHO), the International Labour Organization (ILO), the World Meteorological Organization (WMO) and the UN Environment Programme (UNEP).“The SunSmart Global UV App provides five-day UV and weather forecasts at searchable locations”, said Carla Drysdale, spokesperson for WHO.While speaking today at a briefing at the United Nations in Geneva, Ms. Drysdale added that “it...

Hunting for clues on falling sperm counts, scientists have found ‘alarming’ levels of chemicals in male urine samples
Research into falling sperm counts finds ‘alarming’ levels of chemicals in male urine samples
LONDON — Scientists searching for the causes of falling sperm counts are getting a clearer picture of the role played by chemical pollutants — and it’s not a pretty one.A study of urine samples from nearly 100 male volunteers has uncovered “alarming” levels of endocrine disruptors known to reduce human fertility.Cocktails of chemicals such as bisphenols and dioxins, which are believed to interfere with hormones and affect sperm quality, were present at levels up to 100 times those considered safe.The median exposure to these chemicals was 17 times the levels deemed acceptable.“Our mixture risk assessment of chemicals which affect male reproductive health reveals alarming exceedances of acceptable combined exposures,” wrote the authors of the study, published on Thursday in...

Cancer: Huge DNA analysis uncovers new clues
LONDON — UK scientists have undertaken a huge "archaeological dig" of cancer in the UK, analyzing the complete genetic make-up – or whole genome sequence – of tumors from about 12,000 patients.The team says the unprecedented amount of data allowed them to uncover new patterns in the DNA of cancer – hinting at causes that are not yet understood.They add that the genetic clues will ultimately help improve diagnosis and treatment.The research is published in Science.Cancer can be thought of as a corrupted version of our own healthy cells - mutations to our DNA change our cells until eventually they grow and divide uncontrollably.Traditionally many cancers have been categorized by doctors based on where they are in the body and the type of cells involved - but whole genome...

Unexplained hepatitis cases detected in children in Europe, US
GENEVA — Health officials say they are now investigating unexplained cases of hepatitis in children in four European countries and the US.Cases of hepatitis, or liver inflammation, have been reported in Denmark, Ireland, the Netherlands, Spain and the US, health officials say.Last week UK health authorities said they had detected higher than usual cases of the infection among children.The cause of the infections is not yet known.The European Center for Disease Control (ECDC) did not specify how many cases have been found in the four European countries in total.But the World Health Organization (WHO) said less than five had been found in Ireland, and three had been found in Spain. It added that the detection of more cases in the coming days was likely.Investigations into the cause of the...
